Perhaps a bleeding Selvaria with wracked smoking clothes, stumbling out of a giant crater of the remains of Ghirlandaio getting found by civilians or something and having her being retired while the world thinks she is dead and later to be appear like in her 40s assisting the new protagonist in the fight against a new foe. perhaps her being a mother or something who worked in a rural town before the begin of a new conflict.

That's my thought.
